Length169 mm
Head diameter64.5 mm
Materialaluminium alloy with HAIII hard-anodized finish
Colorsblack

This 360 g flashlight would be considered relatively heavy for a handheld flashlight. Flashlights in this weight range may have features like extended battery life, intense brightness, or rugged construction for heavy-duty use. The length of a flashlight can also impact its balance and weight distribution. A well-balanced flashlight, where the weight is evenly distributed, can be more comfortable to hold for longer periods and reduce hand fatigue.

Aluminium body of L21A SST40 CW is known for its durability and strength. It offers excellent resistance to impacts, scratches, and corrosion, making it suitable for rugged outdoor use or in demanding environments. The HAIII process produces a hard and wear-resistant surface on the aluminum, making it more resistant to scratches, abrasions, and impacts. This improves the overall durability of the flashlight body. The L21A SST40 CW flashlight is available in black.

System

EmitterLuminus SST40 CW LED
Color temperature6500 K
ReflectorSMO
LensAR coated glass
Switchmechanical rear, forward clicky

The emitter of L21A SST40 CW manufactured by Luminus, a US-based LED manufacturer. Luminus is recognized as a reputable LED manufacturer in the lighting industry. They are known for producing high-quality LEDs with excellent performance and reliability. Color temperature is a characteristic of light. It is measured in units called Kelvin (K) and is used to quantify the color appearance of light sources, particularly white light.

The L21A SST40 CW has a smooth reflector. The properly focused smooth reflector gives you a more cohesive hotspot and therefore throws better. This flashlight has an AR coated lens. This Anti-Reflective coating is a thin optical coating applied to the surface of the lens to minimize reflections and improve light transmission. The multiple switch configuration on the L21A SST40 CW flashlight can be a useful option, providing additional versatility and convenience in operating the flashlight.

The L21A SST40 CW has mechanical switch. Mechanical switches are known for their durability and reliability. They are typically built with robust construction, making them resistant to wear and tear, and capable of enduring various environmental conditions. The placement of the rear switch at the end of the L21A SST40 CW flashlight facilitates a secure forward grip. This grip allows for better control and handling of the flashlight, especially in situations where precision and stability are important.

Performance

Flux2300 lm
Intensity129600 cd
Throw720 m
CD/LM factor56.35

With 2300 lm, the L21A SST40 CW flashlight will offer a brighter and more powerful beam of light. This higher output can be advantageous in various situations where you require enhanced visibility or need to illuminate larger areas. 129600 cd represents an extremely high level of brightness for a flashlight. The throw is the calculated distance in meters at which the flashlight produces a light intensity of 0.25 lux. The cd/lm factor (candela-to-lumen ratio) provides information about how concentrated or focused the light output of a light source is. A higher cd/lm ratio indicates that the light is more concentrated in a specific direction, while a lower ratio indicates a more diffused or spread-out light output.

Software

Modes on a flashlight refer to different output settings or levels of brightness that can be selected to suit different needs and preferences. The L21A SST40 CW has mode memory. Mode memory means that the flashlight will remember the mode you were using when the light was last turned off, and when you turn it on again.

The Convoy L21A SST40 CW flashlight is powered by 1 x 21700 Li-Ion battery. The L21A SST40 CW cannot charge batteries directly. You may need an external charger to keep your battery going. This flashlight has a built-in low voltage protection (LVP) to prevent damage to the cell from over-discharge, so protected cells are not necessary. The built-in thermal control automatically adjusts brightness output to prevent overheating. The "8" in the IPx8 rating indicates the highest level of protection against water ingress.

The performance of the Convoy L21A SST40 CW flashlight is measured according to the ANSI / NEMA FL1 Standard 30 seconds after switching the light on. The ANSI/NEMA FL1 2009 Standard is a set of flashlight performance guidelines.
